Key to file and folder names

Main+AGe/Main+HR
-------------------------------------------------
These contain the results for the main models (group + epoch + epoch*group)
and various models with Age or heart rate (HR) as additional variables.
In all models, within-group responses are derived from "epoch" effects, and 
between group effects are based on "epoch*group" effects. ("epoch" is a measure of time.)

HR is the median heart rate in the 1 minute baseline period.
